-- Use the specified toolset located within GHS_TOOLSET_ROOT
-- Update how the latest toolset is determined; scan the location GHS_TOOLSET_ROOT and sort it
No longer use registry settings looking for installations
The registry values are assigned in installation order for Green Hills tools not version order
-- Update to use gbuild.exe from the proper toolset
-- Clarify that CMAKE_MAKE_PROGRAM should not be set by user.
-- Detect some toolset changes when regenerating project files
This could occur if GHS_TOOLSET_ROOT was changed by user after the initial project generation
This could occur if CMAKE_MAKE_PROGRAM was changed at the command line
-- Use placeholder values for CMAKE_<LANG>_COMPILER
The MULTI build system only uses gbuild to build a project
gbuild uses the project file to determine which set of compilers to use based on target platform and architecture
because compiler detection is skipped, placeholder values are used so that CMake does not complain

CMAKE_GENERATOR_TOOLSET
|
|
-----------------------
|
|
|
|
Native build system toolset specification provided by user.
|
|
|
|
Some CMake generators support a toolset specification to tell the
|
|
native build system how to choose a compiler. If the user specifies
|
|
a toolset (e.g. via the :manual:`cmake(1)` ``-T`` option) the value
|
|
will be available in this variable.
|
|
|
|
The value of this variable should never be modified by project code.
|
|
A toolchain file specified by the :variable:`CMAKE_TOOLCHAIN_FILE`
|
|
variable may initialize ``CMAKE_GENERATOR_TOOLSET``. Once a given
|
|
build tree has been initialized with a particular value for this
|
|
variable, changing the value has undefined behavior.
|
|
|
|
Toolset specification is supported only on specific generators:
|
|
|
|
* :ref:`Visual Studio Generators` for VS 2010 and above
|
|
* The :generator:`Xcode` generator for Xcode 3.0 and above
|
|
* The :generator:`Green Hills MULTI` generator
|
|
|
|
See native build system documentation for allowed toolset names.
|
|
|
|
Visual Studio Toolset Selection
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The :ref:`Visual Studio Generators` support toolset specification
|
|
using one of these forms:
|
|
|
|
* ``toolset``
|
|
* ``toolset[,key=value]*``
|
|
* ``key=value[,key=value]*``
|
|
|
|
The ``toolset`` specifies the toolset name. The selected toolset name
|
|
is provided in the :variable:`CMAKE_VS_PLATFORM_TOOLSET` variable.
|
|
|
|
The ``key=value`` pairs form a comma-separated list of options to
|
|
specify generator-specific details of the toolset selection.
|
|
Supported pairs are:
|
|
|
|
``cuda=<version>``
|
|
Specify the CUDA toolkit version to use. Supported by VS 2010
|
|
and above with the CUDA toolkit VS integration installed.
|
|
See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_CUDA` variable.
|
|
|
|
``host=x64``
|
|
Request use of the native ``x64`` toolchain on ``x64`` hosts.
|
|
Supported by VS 2013 and above.
|
|
See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_HOST_ARCHITECTURE`
|
|
variable.
|
|
|
|
``version=<version>``
|
|
Specify the toolset version to use. Supported by VS 2017
|
|
and above with the specified toolset installed.
|
|
See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_VERSION` variable.
